Some good points. The article does elucidate the essential identity of Creationism, PostModernDeconstructionism, and New-Ageism, (along with Scientology and a few others.) All are soul-mates in their desire to destroy the idea that the scientific method is a legitimate means of inquiry.
This sounds like rather a strong statement...
Is this universally true of the adherents to the respective philosophies, or only the more rabid leaders?
By analogy, consider the 'alternative health' or 'preventative nutrition' acolytes who crusade against the medical / pharmaceutical establishment...
Recall there are Nobelists in the sciences who subscribe to nutrition (vitamin C, Pauling) and who challenge paradigms (AIDS, Kary Mullis) who are part of the establishment, all the way down to "channeling and crystal energy healing" people who ARE trying to overthrow science altogether.
Somewhere in your remarks there is an interesting article / book on the various contrasts of various forms of mysticism to disciplined scientific inquiry. Some seek to supplant science; others seek to supplement it; others seek to remove it completely.
OTOH, recall many of the earlier scientists (Brahe, Newton, Faraday) were devout Christians who sought to study Nature so as to better understand the Designer: not that many of the fanatical creationists remember or ever knew this. And Eyring (transition-state theory in chemistry) was a devout Mormon...
And let us not forget Lysenkoism in the athiestic Soviet Union.
Somewhere there was been a parting of the ways between physics and metaphysics. Hence much of the anti-scientific nonsense sprouting since, oh, the 60's and 70's; hence many of the flame wars.
